Subject [jira] [Commented] (HADOOP-13446) S3Guard: Support running isolated unit tests separate from AWS integration tests.
Date Wed, 10 Aug 2016 21:43:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15416068#comment-15416068

Chris Nauroth commented on HADOOP-13446:

bq. Chris Nauroth for the mvn behavior changes you mention, do those only affect build/test
at the hadoop-aws level, or do they impact top-level builds? Seems like the former but making

Good question!  This only impacts the hadoop-aws level.  Only hadoop-aws tests will be using
the verify phase via the failsafe plugin.  (Maybe other modules will start doing it someday
if they have a use case, but that would happen independent of this patch.)

Another consideration is Yetus pre-commit.  That has support for running parallel tests by
passing {{-Pparallel-tests}}.  That's fine though, because pre-commit only runs the test phase,
not the verify phase, and passing {{-Pparallel-tests}} works well for just the unit tests.
 To summarize, there is no harm done to pre-commit.

> Currently, the hadoop-aws module only runs Surefire if AWS credentials have been configured.
 This implies that all tests must run integrated with the AWS back-end.  It also means that
no tests run as part of ASF pre-commit.  This issue proposes for the hadoop-aws module to
support running isolated unit tests without integrating with AWS.  This will benefit S3Guard,
because we expect the need for isolated mock-based testing to simulate eventual consistency
behavior.  It also benefits hadoop-aws in general by allowing pre-commit to do something more
